The SIR scan tool data definitions contain a brief description of all SIR related parameters available on the scan tool. The parameters that are available on the scan tool are listed below in alphabetical order.

Driver Air Bag Res.: The scan tool displays 2.9 ohms, which is the approximate resistance of the inflatable restraint steering wheel module deployment loop.

Ignition: The scan tool displays 0 - 20 volts. This is the system voltage measured by the SDM between the ignition input and ground.

Ignition Status: The scan tool displays the status of the ignition 1 voltage to ensure that it is within the normal operating voltage range.

LH Pretens. Resist.: The scan tool displays 2.5 ohms, which is the approximate resistance of the seat belt pretensioner - LF deployment loop.

LH Side Air Bag Resist.: The scan tool displays 2.4 ohms, which is the approximate resistance of the inflatable restraint side impact module - LF deployment loop.

LH SIS Comm. Error: The scan tool displays whether or not there is a communication error (Error/No Error) between the inflatable restraint side impact sensor - LH (SIS) and the SDM.

LH SIS Init. Status: The scan tool displays the initialization status (OK/NOK) of the inflatable restraint side impact sensor - LH (SIS).

LH SIS Message Status: The scan tool displays the message status (OK/NOK) of the inflatable restraint side impact sensor - LH (SIS).

Passenger Air Bag Res.: The scan tool displays 2.3 ohms, which is the approximate resistance of the inflatable restraint IP module deployment loop.

Reset LH Side Air Bag After Deployment: The scan tool displays whether or not the SDM has been reset (Active/Inactive) after the inflatable restraint side impact module - LF has deployed.

Reset Pretensioner After Deployment: The scan tool displays whether or not the SDM has been reset (Active/Inactive) after a seat belt pretensioner has deployed.

Reset RH Side Air Bag After Deployment: The scan tool displays whether or not the SDM has been reset (Active/Inactive) after the inflatable restraint side impact module - RF has deployed.

RH Pretens. Resist.: The scan tool displays 2.4 ohms, which is the approximate resistance of the seat belt pretensioner - RF deployment loop.

RH Side Air Bag Resist.: The scan tool displays 2.4 ohms, which is the approximate resistance of the inflatable restraint side impact module - RF deployment loop.

RH SIS Comm. Error: The scan tool displays whether or not there is a communication error (Error/No Error) between the inflatable restraint side impact sensor - RH (SIS) and the SDM.

RH SIS Init. Status: The scan tool displays the initialization status (OK/NOK) of the inflatable restraint side impact sensor - RH (SIS).

RH SIS Message Status: The scan tool displays the message status (OK/NOK) of the inflatable restraint side impact sensor - RH (SIS).

SDM Configuration: The scan tool displays whether the SDM is configured for only frontal inflator modules or frontal and side inflator modules.

Warning Lamp: The scan tool displays the status of the air bag indicator.
